Question

The elephant weighs 20,000 N stands on one foot of area 1000 cm2. How much pressure would it exert on the ground?

Answer 1

━━━━━━━━━━━━━━━━━━━━

$\red{ \bf In \: this \: Case}$

$\underline{\purple { \bf Given}}$

• Force (F) = 20000 N
• Area = 1000 cm²

Converting 1000 cm² into m²

☞ $\sf{ \dfrac{1000}{100 \times 100} \: m^{2}}$

☞ $\sf{ \dfrac{1000}{10000} \: m^{2}}$

☞ $\sf{ 0.1 \: m^{2} }$

$\underline{\purple { \bf To \: Find}}$

• Pressure applied

Formula Used :- $\boxed {\red {\sf \bold { Pressure = \dfrac{Force}{Area} }}}$

Subsisting Values

$\longrightarrow \sf Pressure = \dfrac{20000}{0.1}$

$\longrightarrow \sf Pressure = \dfrac{20000}{1} \times 10$

$\longrightarrow \sf Pressure = 200000$

Therefore, we got Pressure 200000 N/m²

In Short, 200k Pascal or 200k N/m²

Answer 2

Given :

• Force (N) = 20,000
• Area = 1000cm² = 0.1m

To Find :

• Pressure

Solution :

Use the Formula :

$\large{\color{grey}{\boxed{\sf{Pressure = \dfrac{Force}{Area}}}}}$

Substituting the values gives :

╭☞ Pressure = $\sf{\dfrac{20000}{0.1}}$

╭☞ Pressure = $\sf{20000 \times 10}$

╭☞ Pressure = 20000pa

So , the pressure is 200000pa or 200000n/m²

Supplementary information :

• Force is something that is push or pull.

• Force is of two types : Contact force and Non contact force.

• Area is the total area an object holds up .

• Pressure is the force of an object that is exerted on something

• Pressure can be measured in Pascals or pa .

• Pressure is Force per unti area : F/A
